No. 61/705,037, filed on Sep. 24, 2012, each of whichapplication is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

There are at least 400 enzymes identified as protein kinases. Theseenzymes catalyze the phosphorylation of target protein substrates. Thephosphorylation is usually a transfer reaction of a phosphate group fromATP to the protein substrate. The specific structure in the targetsubstrate to which the phosphate is transferred is a tyrosine, serine orthreonine residue. Since these amino acid residues are the targetstructures for the phosphoryl transfer, these protein kinase enzymes arecommonly referred to as tyrosine kinases or serine/threonine kinases.

The phosphorylation reactions, and counteracting phosphatase reactions,at the tyrosine, serine and threonine residues are involved in countlesscellular processes that underlie responses to diverse intracellularsignals (typically mediated through cellular receptors), regulation ofcellular functions, and activation or deactivation of cellularprocesses. A cascade of protein kinases often participate inintracellular signal transduction and are necessary for the realizationof these cellular processes. Because of their ubiquity in theseprocesses, the protein kinases can be found as an integral part of theplasma membrane or as cytoplasmic enzymes or localized in the nucleus,often as components of enzyme complexes. In many instances, theseprotein kinases are an essential element of enzyme and structuralprotein complexes that determine where and when a cellular processoccurs within a cell.

The identification of effective small compounds which specificallyinhibit signal transduction and cellular proliferation by modulating theactivity of tyrosine and serine/threonine kinases to regulate andmodulate abnormal or inappropriate cell proliferation, differentiation,or metabolism is therefore desirable. In particular, the identificationof compounds that specifically inhibit the function of a kinase which isessential for processes leading to cancer would be beneficial.

For example, aryl includes 6-membered carbocyclic aromatic rings fusedto a 4- to 8-membered heterocycloalkyl ring containing 1 or moreheteroatoms chosen from N, O, and S. For such fused, bicyclic ringsystems wherein only one of the rings is a carbocyclic aromatic ring,the point of attachment may be at the carbocyclic aromatic ring or theheterocycloalkyl ring. Bivalent radicals formed from substituted benzenederivatives and having the free valences at ring atoms are named assubstituted phenylene radicals.

Numbering does not necessarilycorrespond to that of claims or other tables.

In Scheme A, compounds of Formula I are synthesized by activating thecarboxyl group in A-1 to provide A-2 with a leaving group attached tothe carbonyl. Examples of leaving groups include, but are not limitedto, dimethylhydroxylamino (e.g. Weinreb amide), halogen, alkane- orarylsulfonyloxy, or acyloxy, and the like. In a further embodiment, A-2is a Weinreb amide. In a separate reaction vessel, aryl A-3 is subjectedto a metallation reaction to form metallated aryl A-4. Suitable reagentsfor carrying out the metallation reaction include, but are not limitedto, n-BuLi, sec-BuLi, t-BuLi, t-BuOK, or i-PrMgCl lithium chloridecomplex, and the like. Suitable solvents include, but are not limitedto, tetrahydrofuran, diethyl ether, petane, 1,4-dioxane, methyl t-butylether, and a mixture thereof. Typically without isolation, metallatedaryl A-4 is reacted with compound A-2 to give diaryl ketone A-5. Thereaction is generally carried out at a low temperature, for example, −20to −100° C. After removing the protecting group in A-5, the anilinonitrogen is derivatized to give target compound Formula I. Examples ofprotecting group include, but are not limited to —C(═O)Ot-Bu and—C(═O)t-Bu.

When a chemical entity described herein is administered into a humansubject, the daily dosage will normally be determined by the prescribingphysician with the dosage generally varying according to the age,weight, and response of the individual subject, as well as the severityof the subject's symptoms.

In one exemplary application, a suitable amount of at least one chemicalentity is administered to a mammal undergoing treatment for cancer, forexample, breast cancer. Administration typically occurs in an amount ofbetween about 0.01 mg/kg of body weight to about 100 mg/kg of bodyweight per day (administered in single or divided doses), such as atleast about 0.1 mg/kg of body weight per day. A particular therapeuticdosage can include, e.g., from about 0.01 mg to about 1000 mg of thechemical entity, such as including, e.g., from about 1 mg to about 1000mg. The quantity of the at least one chemical entity in a unit dose ofpreparation may be varied or adjusted from about 0.1 mg to 1000 mg, suchas from about 1 mg to 300 mg, for example 10 mg to 200 mg, according tothe particular application. The amount administered will vary dependingon the particular IC₅₀ value of the at least one chemical entity usedand the judgment of the attending clinician taking into considerationfactors such as health, weight, and age. In combinational applicationsin which the at least one chemical entity described herein is not thesole active ingredient, it may be possible to administer lesser amountsof the at least one chemical entity and still have therapeutic orprophylactic effect.

In some embodiments, the pharmaceutical preparation is in unit dosageform. In such form, the preparation is subdivided into unit dosescontaining appropriate quantities of the active component, e.g., aneffective amount to achieve the desired purpose.

The actual dosage employed may be varied depending upon the requirementsof the subject and the severity of the condition being treated.Determination of the proper dosage for a particular situation is withinthe skill of the art. Generally, treatment is initiated with smallerdosages which are less than the optimum dose of the at least onechemical entity. Thereafter, the dosage is increased by small amountsuntil the optimum effect under the circumstances is reached. Forconvenience, the total daily dosage may be divided and administered inportions during the day if desired.

The amount and frequency of administration of the at least one chemicalentities described herein, and if applicable other chemotherapeuticagents and/or radiation therapy, will be regulated according to thejudgment of the attending clinician (physician) considering such factorsas age, condition and size of the subject as well as severity of thedisease being treated.

The chemotherapeutic agent and/or radiation therapy can be administeredaccording to therapeutic protocols well known in the art. It will beapparent to those skilled in the art that the administration of thechemotherapeutic agent and/or radiation therapy can be varied dependingon the disease being treated and the known effects of thechemotherapeutic agent and/or radiation therapy on that disease. Also,in accordance with the knowledge of the skilled clinician, thetherapeutic protocols (e.g., dosage amounts and times of administration)can be varied in view of the observed effects of the administeredtherapeutic agents (i.e., antineoplastic agent or radiation) on thesubject, and in view of the observed responses of the disease to theadministered therapeutic agents.

Also, in general, the at least one chemical entities described hereinneed not be administered in the same pharmaceutical composition as achemotherapeutic agent, and may, because of different physical andchemical characteristics, be administered by a different route. Forexample, the chemical entities/compositions may be administered orallyto generate and maintain good blood levels thereof, while thechemotherapeutic agent may be administered intravenously. Thedetermination of the mode of administration and the advisability ofadministration, where possible, in the same pharmaceutical composition,is well within the knowledge of the skilled clinician. The initialadministration can be made according to established protocols known inthe art, and then, based upon the observed effects, the dosage, modes ofadministration and times of administration can be modified by theskilled clinician.

The particular choice of chemical entity (and where appropriate,chemotherapeutic agent and/or radiation) will depend upon the diagnosisof the attending physicians and their judgment of the condition of thesubject and the appropriate treatment protocol.

The chemical entities described herein (and where appropriatechemotherapeutic agent and/or radiation) may be administeredconcurrently (e.g., simultaneously, essentially simultaneously or withinthe same treatment protocol) or sequentially, depending upon the natureof the proliferative disease, the condition of the subject, and theactual choice of chemotherapeutic agent and/or radiation to beadministered in conjunction (i.e., within a single treatment protocol)with the chemical entity/composition.

In combinational applications and uses, the chemical entity/compositionand the chemotherapeutic agent and/or radiation need not be administeredsimultaneously or essentially simultaneously, and the initial order ofadministration of the chemical entity/composition, and thechemotherapeutic agent and/or radiation, may not be important. Thus, theat least one chemical entity described herein may be administered firstfollowed by the administration of the chemotherapeutic agent and/orradiation; or the chemotherapeutic agent and/or radiation may beadministered first followed by the administration of the at least onechemical entity described herein. This alternate administration may berepeated during a single treatment protocol. The determination of theorder of administration, and the number of repetitions of administrationof each therapeutic agent during a treatment protocol, is well withinthe knowledge of the skilled physician after evaluation of the diseasebeing treated and the condition of the subject. For example, thechemotherapeutic agent and/or radiation may be administered first, andthen the treatment continued with the administration of the at least onechemical entity described herein followed, where determinedadvantageous, by the administration of the chemotherapeutic agent and/orradiation, and so on until the treatment protocol is complete.

Thus, in accordance with experience and knowledge, the practicingphysician can modify each protocol for the administration of a chemicalentity/composition for treatment according to the individual subject'sneeds, as the treatment proceeds.

The attending clinician, in judging whether treatment is effective atthe dosage administered, will consider the general well-being of thesubject as well as more definite signs such as relief of disease-relatedsymptoms, inhibition of tumor growth, actual shrinkage of the tumor, orinhibition of metastasis. Size of the tumor can be measured by standardmethods such as radiological studies, e.g., CAT or MRI scan, andsuccessive measurements can be used to judge whether or not growth ofthe tumor has been retarded or even reversed. Relief of disease-relatedsymptoms such as pain, and improvement in overall condition can also beused to help judge effectiveness of treatment.
